Title: Plastic tank
Inventor: NAKAZAWA KEIJI
IPC: B65D1/02
Filed: 1982-06-02
Abstract: PURPOSE:To improve the strength of tank and safety by a method wherein inner wall parts of buffer plates are brought in contact with each other, in the captioned plastic tank in which buffer plates are integrally formed by a blow-forming process. CONSTITUTION:A comb-like thin metal plate having a plurality of recesses is projected into the cavity of a blowing mold, a plastic tank is blow-molded to form a connection part 13 between the inner wall surfaces 11' and 12' of the buffer plates 11 and 12. Thereby, even if the stored liquid oscillates in the direction indicated by an arrow to generate a stress P, it is possible to prevent opening/closing of an opening formed after the metal plate is drawn, by means of the buffer plates 11 and 12 integrated with each other. Therefore, strength of the buffer plates as well as safety can be improved.

Title: System and method for data communication
Inventor: MANABE KOJI
IPC: H04N21/4363
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To obtain a data communication system and a data communication method that prevent loss of packetized digital AV data. SOLUTION: An initializing state detection means 60 of a transmitter monitors whether or not an initializing processing circuit of a transmission channel is produced, packetizing means 20, 30 packetize digital AV data. Output of the packetized digital AV data is interrupted under the control of a timing control means 50 for a period when a transmission channel is in a bus reset state, and when the transmission channel is not in the bus reset state, the packetized digital AV data are transmitted to the transmission channel. A receiver connected to the transmission channel receives the packetized digital AV data transmitted from the transmitter to link itself to the transmitter.  Then even when communication between the transmitter and the receiver is once interrupted due to a bus reset or the like, all data packets are transmitted without missing, resulting that video and audio data can be transmitted without interruption.

IPC: B41F31/02
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To shorten a time of an ink replacing operation by merely discarding an ink tray in a wastebasket by removing it from a frame and rounding or breaking it by hand in the case of replacing an ink, incorporating new one in the frame, and mounting it in a printer, thereby easily handling it with a light weight. SOLUTION: The ink tray 1 is constituted by molding a film of a thermoplastic synthetic resin having a thickness of 0.01 to 1.00 mm and a solvent resistance and forming a peripheral wall 3 at an outer edge of a bottom plate 2. Since it is formed of a thin material, it is contained in a light-weight frame obtained by bending a metal gauze or a metal pipe for use at the time of printing. In the case of replacing the ink, it is removed from the frame, rounded by hand or broken, and discarded in a wastebasket. Then, new one is contained in the frame, and merely mounted in the printer.

Title: Electrostatic induction thyristor
Inventor: OOTSUBO YOSHINOBU
IPC: H01L29/78
Filed: 1984-05-14
Abstract: PURPOSE:To improve turn ON characteristics, turn OFF characteristics, di/dt resistance and dv/dt resistance without increasing ON voltages, by providing a gate coupling region, which connects neighboring gate regions, in channels. CONSTITUTION:At the central part of channels 8, a gate coupling region 12, which connects grid shaped neighboring gate regions 5, is provided. In the vicinity of the gate coupling region 12, which is farthest from a gate electrode 10, current concentration due to the delay in turn OFF operation occurs. At this time, the resistance from the current concentration point to the gate electrode 10 through the gate region 5 is decreased by the gate coupling region 12. By this action, the current value, which can be drawn to the gate electrode 10, is increased. Therefore, the allowances of a controllable current and an anode voltage generated in a falling period can be increased. Meanwhile, the decreasing rate of the channel area by the gate coupling region 12 is small. Therefore the gate resistance is decreased by the gate coupling region 12. Thus dv/dt resistance is improved. Since the time constant of the gate region becomes small, turn ON characteristic and di/dt resistance can be improved.
